METAL-FOIL EN VELOP OR CONTAINER Specification of Letters Patent.

Patented June 22, 1915.

Application filed November 20, 1913. Serial No. 802,104.

To all whom it may concern:

Be it known that I, ADOLF BRYNER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Metal-F oil Envelope or Containers, of which the following ,is a specification.

This invention relates to an envelop or container within which articles and substances of various kinds my be securely protected from the action of the atmosphere, deterioration or loss through evaporation and destruction by the entrance of fluids of any kind into the envelop and has for its object to provide a container made of a sheet of metal or an alloy of metal fusible at a low temperature which may be folded over the article to be preserved, preferably with a single fold, the outer margins of the folded portions of said sheet overlapping and extending in the same direction in contact with each other and inseparably secured together by fusing the contacting surfaces adjacent the edges thereof, forming a joint or connection that hermetically incloses the substances within the envelop. In place of a folded sheet, two sheets of similar shape may be employed with their edges coincident and their entire overlapping margins fused together.

In the accompanying drawings: Figure l is a face view of the preferred form of sheet for making the envelop. Fig. 2 is a top View of the envelop complete. Fig. 8 is a perspective view of the complete envelop with a portion broken. from the center thereof.

In the drawing, a sheet 5 of very thin metal or metal allo preferably a relatively heavy and flexible oil, and circular in form, is placed upon a flat surface and the article or substance to be inclosed therein is placed on the sheet. The sheet is then folded on its diameter. The margins 7, 7 of the two folded portions of the sheet are placed in contact, one upon the other and extending both in the same direction with their edges substantially coinciding. The margins are now sealed by a suitable tool, heated to the proper tem erature by any convenient means, passe around said'margms from one end of the fold 8 to theother with sufficient pressure to brin them into close contact, and by means 0 the heat of the tool,

cause a softening of the contacting surfaces and a fusion thereof as at 9. The joint or seam thus formed unites integrally and solely with the original substance of.the

sheet the entire overlapping margins of the folded sheet and forms a container of a sin- The sheets as stated are preferably circular, but may be rectangular, as indicated v by the dotted lines 10, or of other shape which should, however, be a regular form, so that when two layers of the foil are brought together the edgeswill substantially coincide.

An envelop or container as thus made provides absolutely perfect protection for any material that is affected or destroyed by exposure to the atmosphere or to moisture; that evaporates when open or imperfectly incased or sealed, and which is subject to change on exposure to light. The tin foil envelop being impervious to light, air and moisture, and the fused margins being in" separably connected by a homogeneous union of the two surfaces of the folded sheet, any substance inclosed within such an envelop will be indefinitely preserved.

What I claim is 1. As a new article of manufacture, a hermetically sealed metallic envelop or container, consisting of a thin sheet of pliable metal fusible at low temperature, folded upon itself and about the article or substance to be inclosed, with the marginal edges of the sheet contacting and extending in the same direction and integrally united by a metallic seam composed wholly of fused metal'portions of the sheet. I

2. As a new article of manufacture, 8. hermetically sealed package or container comprising two layers of relatively heavy metallic foil superposed one upon the other with their marginal edges coinciding and inte rally united by a metallic seam composed solely of fused metal portions of said layers.

3. As a new article of manufacture, a hermetically sealedpackage or container consisting of a circular sheet of relatively heavy flexible metalfoil fusible at low temperature, said sheet being folded upon itself about the article or substance to be inclosed,

Q mieeee the two semi-circular margins of the folded In testimony whereof I have hereunto set sheet overlapping and extending in the same 111. hand in presence of two subscribing 1o direction with their outer curved edges sulo- Witnesses.

stantially coinciding end inseparably united ADOLF BRYNER by a continuous metallic seam composed solely of fused metal portions of the sheet, Witnesses:

said seem extending entirely around the J OHN L. CLUNE,

said semi-circular margins of the package. THOMAS E. AMBROSE.
